Received the "Lang" branded product (Lang is transitioning away from the Kastar branding for its tools). Outside label and inner components list indicate "made in U.S.A." origin... AND the grey plastic storage unit is HINGED... plastic, but not the so called "lifetime" type that ultimately fails over time! *The thread chasing taps and "die nuts" appear to be well machined with no obvious defects/dings on their machined threaded surfaces. *Overall appearance in terms of lack of "machining marks" and burrs is quite good to excellent. *This set has more components than some, and covers popular SAE Course, SAE Fine Thread, and Metric size fasteners, with each type a different color for ease of identification. *There will certainly be instances that a "desired" thread configuration isn't in the kit, but for most of us, this kit covers virtually anything we typically have to deal with in terms of chasing threads (within the size range this kit covers... 1/4" to 5/8 " SAE and similar sized Metric). I would loved to have seen #10 size fasteners covered, but really can't complain... none of the other "sets" I've seen over the years included them either. * The only "negative" is a very minor one for me... The stamped size identification on some of the smaller die nuts is a little hard to see without magnification. Keep in mind that the smaller dies leave little room for marking purposes, and the black colored "SAE fine thread" ones don't provide for contrast in color. That said... each die nut item has its own "storage indention" in the plastic tray, that is sized according to the size of the nut...AND the fractional or metric size is clearly observable on the tray in raised numbers when the dies are removed...plus the fine thread/course thread/metric thread aspect is already identifiable based on the component color. Should not EVER be a problem except for the most picky of users! Finally...AND THIS IS A BIG ONE: As some other reviewers have already mentioned...TOOLS OF THIS TYPE ARE NOT FOR CREATING NEW THREADS! If you need this utility... buy a tap and die set! Items like this LANG produced set are primarily for "chasing" existing threads. I use the Chase Taps for helping to remove dried thread locker and thread sealant from female threads... as well as moderate corrosion and rust. This is useful to assure that new threadlocker or sealant has a good surface to bond with, and also helps minimize any negative impact on torque requirement (especially for inch-pound specified fastener situations). A shot of compressed air, or a "spritz" of brake cleaner to degrease the threads completes the process. The Chase Dies are ideal for removing excessive debris (rust, dried thread locker, etc.) from bolts... and are useful for helping to "rehabilitate" slight ding type defects on the threading. Keep in mind that trying to rehabilitate damaged hardened fasteners, alter an existing thread pitch, "re-thread" a badly damaged bolt, or try to extend the threaded depth of a hole is ABUSIVE to the product. AGAIN... these are not highly hardened tool steel items intended for cutting new threads. They do a GREAT JOB for their intended purpose, and allow the user clean up existing threads without cutting away material (and thus adversely impact fit or strength). Tools such as this are designed to "complement" a good tap and die set...NOT replace them! "Well done" Lang Tools...this set is precisely what I need... my old set had fewer sizes available and over the years was "missing a couple" due to loss or simple misplacement!

These Lang thread restorers/chasers are about the best you'll get for your money, and Lang is well known for making some of the best thread chasers on the market. No missing pieces and everything seems well machined. The machining on the shafts of a few metric taps are a little bit uneven. It's not enough that I worry the tool is compromised in any way, but it was enough to notice and hope the manufacturer will take note and attempt to improve quality as all manufacturers should when a concern is raised. It's important to know what these are for. These are not for cutting new threads, but for restoring threads that may be rusted, dirty, or slightly damaged. If your threads are completely ruined, you'll need to use a threaded insert or drill and tap the hole to a larger size. You can use a wrench or a socket on these, but be gentle. I would recommend a small 1/4 drive ratchet if possible as it will prevent application of too much torque. You don't want to break these as it will make your situation more frustrating. There isn't much information listed about the warranty. Keep in mind that these are technically consumable items, over time and enough use, they may need to be replaced. That said, based on the reputation this brand has as well as the testimony of other customers, I have confidence the seller would replace them if there was an obvious defect within the lifetime of the tool. Overall, I'm happy. If I have issues with these in the future I will report back.

Resist the temptation to buy a cheap set. This is a good mid-range, made in USA quality set. Sizes covered just about anything you're going to need. Yes there are more expensive brands, but you pay for the name. I've used this set extensively it is held up very well. Just remember to use cutting oil and this will be the last set you need to buy. Highly recommend it.

I needed to clean up a hub that had bolts cross-threaded in it. This worked great. In the past I've used taps for such, but not owning a set I tried to decide which one to purchase, and lots of folks recommended NOT using taps to clean out /deburr existing threads, recommending a "thread chaser" or "thread restorer". They also noted that Kastar made a good kit, and it was rebranded Craftsman, SnapOn, Mac, etc... (I do not know this to be true, or not, but the kits DO look identical in tool placement, description, etc...). One important note - I ordered the Kastar kit and received a Lang - at first I thought this was a seller mix-up, but a quick google search revealed Lang and Kastar are now one, and all the tools are being branded Lang now... and the case is grey, not red. Everything else appears the same. The taps did seem a little "rough" when I first started using them, but after a few turns "broke in" nicely and did an excellent job (I used a little cutting oil to ease the work - and help clean things out. Some of the 6 holes were pretty bad). Reason for 4 instead of 5 stars - I used a bit of solvent after each hole to re-clean the tap and the finish appears to be coming off (I was using the 14mm tap... "gold") They are stamped anyway, so it isn't a functional problem, but given how they are typically used I would have thought the finish wouldn't disappear quite as quickly.

This is an essential safety net to have. Lang tools have impressed me in the past, and they have this time as well. This is just done right in every way

This thread chaser set is just as described. Included all the parts I expected. Mine was Lang branded. Made in USA. The machining on the tools is very clean. The hard case feels sturdy enough. The plastic clasps might wear out overtime though. Every piece has a clearly marked place in the case. No detailed instructions included, but you can always watch some videos online. I've already cleaned up some damaged bolts. Looking forward to cleaning up damaged threads on my car.
